Motivated by the need to eliminate expensive rare-earth magnets in utility-scale direct-drive wind turbines, Sandia National Laboratories researchers have developed a fundamentally new type of rotary electrical contact. Most of the current utility-scale wind turbines are dependent on rare-earth magnets, Koplow said. 1 milliohm).
